Give me your thoughts and comments about the procedure?
Did it go fairly easy or was it a headache of a job?
Were you able to do it with tools you’d find in your avg Joe tool box?
Did the kit come with everything you need or did you have to run back and forth to NAPA or somewhere else to get everything you needed?
Did your brake lines take the added pressure or would I find myself replacing those as well?
BTW, what happens if your car stalls? Occasionally if I have to hit the brakes fast I stall

I don't have a Hydratech, but am working on moding a GM Safari hydroboost to work. The only question I can answer is about loss of engine power. These systems were designed for production vehicles so they include safety backups. There is a nitrogen reservoir that assists in the event of engine power loss. It's the gold canister looking thing on the hydroboost.

I put one of Paul's units into my '65. It was a no-brainer! Took more to get the old booster out than to get the hydroboost in. I didn't even take out the master cylinder, left all the brake lines still attached. The one thing I didn't like with the kit was the "T" fitting for the return lines to the power steering pump. My solution was to find a pump that had 2 return tubes in the can instead of 1. My can came off a mid 70's Caddy w/hydroboost (I think). I found it in a power steering pump catalog at Autozone and found one that was the same can style and ordered it. The pump in it was NOT compatible (pressed on pulley verses mine held on with a nut) so I just swapped out the pump guts and then bolted it right up. Looks all stock, and will be even more so when I get some custom pressure lines made up to replace the stainless ones. I swapped all the pulleys on my 406SBC for deep groove ones and used a corvette cast iron pulley to drive the pump. I have 12" vette calipers/rotors up front and 11" drums in the rear and stops are quite nice now. My car use to stall when slamming on the brakes, not after installing the hydroboost. The hydroboost unit also has an "accumulator" that will allow the brakes to work for a couple of pumps.

That because what little vacuum you did have your not using it with the power brake booster?

got one on my 70 and even working around the intercooler piping for my procharger it went very smoothly. kit had EVERYTHING i needed for the job and instructions were nice and clear IMO. an average toolbox should have all the tools needed. the resevoir on the set-up is supposed to store enough pressure for roughly 3 stops once the car has died. 1 at approx 85%, 1 at 60% etc. as far as the braking....WHOA!!! i can stop that thing better with my big toe now better than i could have ever imagined with both feet before. the steel lines can of course handle the pressure and i already have stainless brake lines on the car and for as inexpensive as they are i cant see why anyone wouldnt run them. just call paul over @ hydratech and talk with him. he was a super nice guy on the phone and really seems to know his stuff. ill try and post a few pics of my set-up later tonight.

Get one from Hydratech. I got one earlier this year. The entire installation took me less than 2 hours and I was taking my time. It is by far one of the best upgrades that I have done to my car yet. The only issue that I had with the Hydratech package was that I needed to cut the braided steel hose. I couldn't get the ends on so I finally just took them to a hyrdaulic hose shop by my house. $10 and 15 minutes later they were done and the perfect size. Over all it was a great experience.
